I propose to rename the tag dynamic (currently 8 questions) to dynamic-algorithms (currently nonexistent), because the questions with the tag are really about dynamic algorithms, that is, algorithms about certain objects with online updates.
I cannot use the existing system for creating a tag synonym (which would automatically merge the created tag synonym to the real tag) because the tag dynamic-algorithms does not exist at this moment. Therefore, I would like to invoke the official interim procedure for doing retagging for this purpose. This means:
I do not think that the old tag dynamic should be a tag synonym after renaming, but I do not have a strong opinion about this.
